Nothing at I have seen in print. However, every summer and early fall they have renos going on. My guess would be the TRS or Bavaro sections because Punta Cana and Palace have recently had renos done. Most likely the renos will be "facelifting" (painting etc)

From my experience, Palladium never announces when construction is going to take place. The resorts are so big with redundant services (pools, restaurants,theaters) that it has never really affected our stay and we usually travel in the Summer when they do most of their work. The only exception is when Riviera was converted TRS and the dump trucks using the walking paths was annoying.
